I am a complete neophyte when it comes to lawn mowers. Inherited one from father in law which had been sitting around for 2 years. Worked for 5 minutes then died. Neighbor told me to get some carb spray which I did. Sprayed it, white smoke came out and it worked fine. Mowed the lawn like 3 times and then last week ran out of gas. Filled up and it began sputtering. Finally died and was not able to start again. Neighbor again recommended some gas stuff. Bought that put in and before i could test, cord broke. Finally fixed that today. Starts ok but as soon as I switch from choke to Fast on throttle, dies out. BTW- this is a Honda 215HXA. Any help in Lawnmowers for Dummies variety would be appreciated.
